The Chem-Tainer 1500 Gallon HDPE Vertical Liquid Storage Tank is a 1500-gallon vertical storage tank molded in natural white polyethylene, standing 127 inches tall on a 64 x 64 inch footprint. It carries a 1.9 specific gravity rating, which is the heavy-duty wall build: full of water it holds roughly 12,510 lb of contents, and at its rated 1.9 specific gravity it is engineered for liquids up to 23,769 lb. If you are sizing a vertical tank for bulk water, rainwater capture, or a fire-water reservoir, those two weight figures are the numbers your pad and your fittings have to be designed around.
Will this tank work for your application
This is a vertical liquid storage tank built for atmospheric storage. Before anything else, confirm two install numbers in one glance:
- Height clearance: 127 in tall (about 10.6 ft), plus working room above the lid for the fill and vent.
- Pad footprint: 64.0 x 64.0 in, level and continuously supported.
- Foundation load: plan for 12,510 lb full of water, up to a 23,769 lb rated contents ceiling.
The 1.9 specific gravity rating is what separates this build from a lighter water-only tank: it is engineered to carry contents denser than water up to that rated weight while still handling a full water column. If you are only ever storing plain water, this is more wall than you strictly need, so it is worth checking whether a lighter-rated version of this size fits your job before you commit. To match the tank to your draw rate and storage duration, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide.
Specs and fittings that drive the install
Height is 127 in, width and length are each 64 in, and the foundation should be a level, continuously supported concrete or compacted pad sized to the 64-inch footprint. The technical drawing on this page is the source of truth for fitting locations, outlet placement, and lid size, so confirm those positions against your plumbing run and confirm overall dimensions before you order any connections. If you are weighing this size against other brands, our Snyder vs Norwesco vs Chem-Tainer vertical storage tank comparison walks through how the major manufacturers stack up in this class.
One thing not to get wrong
The mistake to avoid on a tall vertical like this one is venting. A 1500-gallon tank moves air fast during quick fills and gravity draws, and an undersized vent can pull a vacuum on the wall or pressurize the headspace. Our worked examples in Atmospheric Vent Capacity Calculations for Polyethylene Storage Tanks cover thermal inbreathing, outbreathing, and combined sizing for 1500-to-10000-gallon verticals. If this tank is feeding a rural fire-protection setup, our fire-water reservoir tank design guide covers NFPA 22 sizing and cold-climate freeze protection. And because vertical tanks fail first at the vapor-saturated headspace, the HDPE wall-thickness guide is worth reading on inspection.
This vertical storage tank ships LTL freight, quoted live to your ZIP from the nearest of four stocking plants (Marked Tree, AR; Hanford, CA; Hummelstown, PA; and Lake Wales, FL), so your freight is built off the closest origin rather than a cross-country haul.
